Ten days into the March 2026 core update, most SEOs are still checking their Analytics dashboards without understanding the pattern. YouTube traffic is up across every major country-US, India, France, Germany-while informational content mills are hemorrhaging keyword positions by the tens of thousands. This isn’t a ranking fluctuation. It’s a signal about what Google considers valuable in 2026.
Why YouTube and Instagram Are Winning the March 2026 Update
YouTube now generates a double win: videos rank in the video carousel and get cited directly inside AI Overviews, creating two distinct organic traffic streams from a single asset. This dual-placement advantage explains why YouTube saw record-breaking organic traffic gains across nearly every country, according to Kasra Dash’s analysis. The platform doesn’t just occupy SERP real estate-it feeds Google’s AI summary engine.
Instagram Reels entered the game roughly 9 to 10 months ago when the platform opened indexing to Googlebot. Now Reels appear in Google’s top 10 results for short-form queries. When you search Google Shorts, the results pull a mix of YouTube and Instagram Reels, making short-form video a mandatory channel post-update.
Compare this to TikTok’s relationship with Google: while TikTok videos occasionally rank, the platform’s indexing agreement remains limited, and content doesn’t flow into AI Overviews the way YouTube’s does. Instagram’s integration is newer but growing faster in SERP visibility.
The Wikihow and Grokopedia Collapse: What 100,000 Lost Keywords Tells You
Wikihow lost approximately 100,000 keyword positions in under 10 days, a decline that reveals the fatal flaw in building a site purely on long-tail informational content. When your entire model depends on answering “how to” queries with generic step-by-step instructions, you’re vulnerable the moment Google decides those answers already exist elsewhere.
Grokopedia’s traffic dropped from 800,000 to 630,000 organic keywords because it rehashes information Google has indexed hundreds of times. The site adds no new data, no original research, no first-hand testing. It’s a content aggregator in an era when aggregation without insight is penalized.
The pattern is clear: if your content could be written by someone who’s never touched the product, never run the test, and never spoken to a real user, Google will rank someone else who did those things.
What Information Gain Actually Means (And Why AI Content Fails Without It)
Information gain means being the first to publish new data, original reviews, product announcements, or proprietary research-content that adds something to the internet’s knowledge base rather than restating what’s already there. When you’re first, Google has a reason to prefer your site. When you’re fifth to publish the same take, you’re competing for scraps.
AI content writers alone won’t protect your rankings if they’re simply repackaging existing information without adding anything new. The tools can speed up production, but they can’t manufacture originality. They can’t interview a customer, run a benchmark test, or break news.
This is where human-AI collaboration wins: use AI to structure, draft, and optimize-but feed it original inputs. Proprietary data from your analytics. Customer interview quotes. Before-and-after case study results. The AI handles the formatting; you supply the information gain.
| The Industry-Standard Approach | The Authority Approach |
|---|---|
| Mass-produce AI articles targeting long-tail keywords | Publish fewer pieces with original data, case studies, or first-hand testing |
| Rewrite competitor content with slight variations | Add proprietary insights competitors can’t replicate without doing the work |
| Focus on single content type (blog posts or videos) | Balance long-tail articles, comparison keywords, service pages, and multimedia |
| React to core updates by pruning low-traffic pages | Use Ahrefs Position History to reverse-engineer what winners changed |
| Optimize for keyword density and on-page SEO | Optimize for information gain and being cited in AI Overviews |
How to Use Ahrefs Position History to Reverse-Engineer Update Winners
Ahrefs Position History lets you identify competitors that gained rankings after a core update and reverse-engineer exactly what content changes they made. Filter by keywords that jumped 10+ positions in the last 30 days. Export the list. Visit each URL and compare the current version to a Wayback Machine snapshot from before the update.
Look for these signals:
- Did they add original data, charts, or statistics not found elsewhere?
- Did they embed video content or interactive elements?
- Did they add expert quotes, interviews, or first-person experience sections?
- Did they restructure headings to match featured snippet formats?
- Did they add comparison tables or product testing results?
The winners aren’t guessing. They’re adding information gain in specific, repeatable ways. Your job is to identify the pattern and apply it to your own content before the next update.
Why a Balanced Content Strategy Survives Core Update Volatility
A balanced content strategy combining long-tail articles, comparison keywords, and service or product pages is more resilient to core update volatility because it doesn’t depend on a single ranking mechanism. When Google devalues one content type, your traffic doesn’t collapse-it shifts.
Long-tail informational posts still work, but only when paired with:
- Comparison and “vs” keywords that help users make decisions
- Service or product pages that convert traffic into revenue
- Video content that ranks in carousels and AI Overviews
- Short-form content (Reels, Shorts) that captures mobile search intent
Sites that survived the March 2026 update had portfolio diversity. They weren’t 100% how-to articles or 100% product reviews. They mixed content types, which meant no single algorithmic shift could wipe them out.
Frequently Asked Questions
How do I know if my content has enough information gain to survive the next update?
Run this test: could a competitor replicate your article’s value by reading three other articles on page one? If yes, you lack information gain. Add proprietary data-customer survey results, original benchmark tests, expert interviews, or case study metrics-that competitors can’t copy without doing the work themselves.
Should I delete old informational content that’s losing rankings?
Not immediately. First, check if the content can be upgraded with information gain. Add original research, embed a video walkthrough, or include a comparison table with real product testing. If the keyword intent has shifted to video or AI Overview answers, consider redirecting the URL to a related service page or video asset instead of leaving it to decay.
Can I still use AI content tools after this update?
Yes, but change how you use them. Don’t ask AI to “write an article about X.” Instead, feed it your original inputs-interview transcripts, test results, proprietary data-and ask it to structure and optimize that material. The AI becomes a formatting assistant, not a content creator. This keeps production speed high while ensuring information gain.
How often should I check Ahrefs Position History after a core update?
Check daily for the first 10 days of a core update rollout, then weekly for the following month. Core updates take 2-4 weeks to fully settle. Early movers who reverse-engineer winners in the first week can implement changes while the algorithm is still adjusting, sometimes capturing rankings before competitors notice the shift.
Do Instagram Reels need special optimization to rank in Google?
Yes. Use keyword-rich captions, add alt text to your profile image, and include relevant hashtags that match search intent. Google can’t watch your Reel, so it relies on text signals. Also, cross-post high-performing Reels to YouTube Shorts with optimized titles and descriptions to maximize your chances of appearing in Google Shorts results.
What’s the fastest way to add information gain to existing content?
Conduct a single original test or survey related to your topic and publish the results as a data section within your article. Even a small sample size (50-100 responses) gives you proprietary statistics competitors don’t have. Pair the data with a simple chart or graph, and you’ve added measurable information gain in under a week.
